eac1ca22bd imx233: generate register headers using headergen_v2 and update code for it
NOTE: this commit does not introduce any change, ideally even the binary should
be almost the same. I checked the disassembly by hand and there are only a few
differences here and there, mostly the compiler decides to compile very close
expressions slightly differently. I tried to run the new code on several targets
to make sure and saw no difference.

The major syntax changes of the new headers are as follows:
- BF_{WR,SET,CLR} are now superpowerful and allows to set several fileds at once:
  BF_WR(reg, field1(value1), field2(value2), ...)
- BF_CS (use like BF_WR) does a write to reg_CLR and then reg_SET instead of RMW
- there is no more need for macros like BF_{WR_,SET,CLR}_V, since one can simply
  BF_WR with field_V(name)
- the old BF_SETV macro has no trivial equivalent and is replaced with its
  its equivalent for BF_WR(reg_SET, ...)

I also rename the register headers: "regs/regs-x.h" -> "regs/x.h" to avoid the
redundant "regs".

Final note: the registers were generated using the following command:
./headergen_v2 -g imx -o ../../firmware/target/arm/imx233/regs/ desc/regs-stmp3{600,700,780}.xml

4604e984e8 imx233: rework i2c driver to fix dma issues
There are tricky DMA/cache related issue on the imx233 which could
pop up with the old driver. The new one ensures that all dma
tranfers are cache safe by using an intermediate buffer.

9caffa8bf7 imx233/fuze+: rework i2c and fmradio_i2c init
Only enable fmradio_i2c once with _init() called from system.
Move actual i2c init to system for consistency.
Move tuner power pin setup to power instead of fmradio.
